Yes I think I can hear the radiator fan. It is a very faint low roaring sound, in contrast to the cycling high pitched dash AC condensor fan that I know about
Maybe I can hear the radiator fan because I have a walk-in closet instead of a rear bath? Also maybe I have a different engine, Cummins 360. I guess my main question was whether your temp. guage needle fluctuates between the 1/2 and 3/4 mark while driving at 65 mph. Thank you for your replies.
